6x-2(3x+2)=-4.
that would reduce after distributing the negative two to the parentheses as:
6x-6x-4=-4.
that can be reduced because the x’s cancel out. when you move the -4 over by adding 4, those cancel out too. therefore, the answer is infinite. hope this helps!!
Answer:
No
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to the normal distribution if
and
In this problem, we have that:
First condition
Second condition
Multiplying by -1
p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.
In given picture we see that there are total 8 boxes out of which only 5 are shaded.
So the number that represents shaded part will be 5/8.
But we have to find which choice doesn't indicate shaded part.
So we will pick those choices which are not equivalent to 5/8.
5/8=0.625
if you convert that into percent then we get (5/8)100%=62 1/2 %
that means 5/8, 0.625, 62 1/2 % all represents same thing and represent shaded part.
So the remaining choice a) 0.582 is the final answer .
Answer:
4 years
Step-by-step explanation:
Given data
Principal P=$5000
Rate r= 7.5%
Final amount A=$6500
The expression for the simple interest is
A=P(1+rt)
Substitute
6500=5000(1+0.075*t)
6500=5000+375t
6500-5000=375t
1500=375t
t= 1500/375
t= 4 years
Hence, the time is 4 years
